How can you save all or a portion of the Grafics object to a Image/Bitmap ?
I am try to save the Images from Cards.dll to a BitMap file.
I can read in the Images to the Grafics, but when I try this with a Bitmap
the results are Black.
Can you somehow Clip the Grafic and Paste it into the Bitmap ?

I am writing a service that will create a bitmap image and return it to the
client. First, I wrote a method that looked like this:

I have a helper class that has a method to resize images. It takes the

I have the following class I use to save Tiff's. The problem I have with it
is that the final size of the images are very large. If we scan directly to a
file the final tiff may be 600-900 kb.s but with this code it is often
4000-5000 kb.s. What am I missing?
public class EmrTiff : IDisposable
{
private string fileName;
private ArrayList imageContainer = null;
